“…Additionally, considering a typical probability distribution profile of a daily CNG refueling operation [41], the cooling power profile shows a trend as that depicted in Figure 2. The profile provided in Figure 2 was therefore selected as the cooling supply side availability for the DCS.…”

“…The last case, shown in Figure 2c (P3), introduces a variable profile with a peak power in the evening. In fact, as Farzaneh-Gord et al [32] highlighted in their analysis by monitoring the number of refueling CNG vehicles in a day, a peak is generally observed between 6 and 7 p.m. This last scenario is therefore introduced to consider a variable cooling power during the day.…”

District cooling systems (DCSs) are networks able to distribute thermal energy, usually as chilled water, from a central source to industrial, commercial, and residential consumers, to be used for space cooling/dehumidification. As cooling demand will increase significantly in the next decades, DCSs can be seen as efficient solutions to improve sustainability. Although DCSs are considered so relevant for new city developments, there are still many technical, economic, and social issues to be overcome to let such systems to spread out. Thus, this paper aims to highlight the advantages and issues linked to the adoption of DCSs for building cooling when cold is recovered from a specific application. A case study based on liquified natural gas (LNG) cold energy recovery from the transport sector is presented. Starting from the estimation of the free cooling availability, a DCS design method is proposed and the potential energy saving is investigated. Results show that a DCS using the cold waste derived from LNG can provide a relevant amount of electricity saving (about 60%) for space cooling compared to traditional solutions, in which standard air conditioning systems are installed in every building.

“…The natural gas installation part consists of two CNG tanks, 60 dm 3 each (7). This type of tank is actually used in CNG NGV installations [23]. Each CNG tank is equipped with: a check valve (4) which prevents through backflow during fueling; electronic shut-down valve (6) which cuts off the CNG tank from the rest of the installation to prevent natural gas flow in case of leakage and/or an emergency event; manometers and pressure transmitters (5).…”

Compressed natural gas can be globally used as fuel for combustion engines to reduce CO2 emission without negative impact on economy. Lack of refueling infrastructure is one of reason why NGVs shares only ~1.6% in total vehicle fleet worldwide. Operational tests of CNG home fast refueling station were performed to investigate: (i) natural gas demand, m3/h; (ii) energy consumption, kW/h; and (iii) total cost of one refueling. Two scenarios for operational tests were developed to monitor and collect data. Safety tests for leakage, fill pressure change, interrupted power and gas supply, temperature, and unexpected failures were performed. This article present results of operational and safety tests of compressed natural gas home, fast refueling station (CNG-HRS) based on one stage hydraulic compressor. The average duration of HRS full operating cycle was 7 h and 32 min (buffering and refueling mode). The average electric energy and natural gas consumption for one full cycle was 5.52 kWh and 7.5 m3, respectively. Safety tests results for leakage, fill pressure change, interrupted power and gas supply, temperature and unexpected failures demonstrated valid operation of HRS which positively affects the general safety level. To compare HRS with large scale CNG refueling infrastructure the costs of 1 Nm3 CNG was estimated for both solutions. Results shows that home refueling appliance might be become a solution for filling the gap in CNG refueling infrastructure.
